3-2-2 Security Tab
The Atheros Client Utility provides four types of encryption: Pre-Shared Keys,
LEAP, Externally Managed 802.1x Keys and Disabled.
Each wireless device within a WLAN must use the same security settings to
allow communication. Depending on whether you are connecting to an Ad Hoc
or Infrastructure network, you will need to consult one of the workgroup
participants or network administrator for the correct security settings.
3-2-2-1 Pre-Shared Keys
To use this option, enable the Pre-Shared Keys option on the Security tab and
click Define Pre-Shared Keys to set the encryption keys. Then configure the
fields below:
Key Entry Method: Select the method to enter the key. If Hexadecimal is
selected, only digits 0-9 and letters a-f, A-F are allowed. If ASCII Text is
selected, you can enter alphanumeric characters.
Key Length (bit): Defines the length for each encryption key. Key length varies
according to the WEP type. As the Key Length is changed, the number of
available characters in the field is changed automatically. If an already entered
key is too long, the key is automatically truncated to fit. If the key length is
increased again, the field does not automatically restore to its previous value.
Per-User Key: Defines the unique encryption key for network configuration
security. This field must be populated to enable security using a unique key. This
key is not used in Ad Hoc mode.
Shared Keys (1 ~ 4): Defines a set of shared encryption keys for network
configuration security. At least one Shared Key field must be populated to
enable security using a shared key.
Note
All encryption key fields are displayed only when initially entered. On
subsequent entry into the security property page, the field are masked.
Select the default encryption keys to be used (either Per-User Key or Shared
Key). You are only allowed to select one Per-User Key, or one Shared Key 1,
Shared Key 2, Shared Key 3, or Shared Key 4 whose corresponding field has
been completed.
